Definitions

  • the present invention relates to an electronic cigarette (e-cigarette) device, and more particularly to an electronic cigarette which has separated driving passage and vapor passage.
  • Electronic cigarette utilizes battery for power supply to the heating element which process heating and atomization of the e-liquid. Then, the aerosol from atomization of e-liquid is inhaled through the mouthpiece of the e-cigarette. Accordingly, the effect similar to smoking is achieved. Through reasonable mix and ratio of the ingredients of the e-liquid, the effect of quitting smoking or alternative smoking is achieved.
  • the e-cigarette Amongst the e-cigarette products, there are two ways to start. One is to use an external switch to start the atomizer of the e-cigarette but the operation is troublesome. At present, the e-cigarette mostly uses another method, which is, adding a pneumatic switch on the airflow channel of the e-cigarette. The airflow generated during vaping can start the atomizer of the e-cigarette directly. In this way, the vaping experience is similar to actual smoking. When the e-cigarette is in use, liquid such as condensate and penetrating vape oil is generated. If the liquid flows to the pneumatic switch through the airflow channel, the pneumatic switch will be damaged and the life of the e-cigarette is shortened.
  • An object of the present invention is to provide an electronic cigarette which can prevent the backflow of condensate and oil of the e-liquid into its pneumatic switch and prevent damage to the pneumatic switch, while the sensitivity of the pneumatic switch is not affected by the diameter of the airflow channel of e-cigarette.
  • an electronic cigarette which comprises a battery component, an atomization component, a pneumatic switch which controls the starting of the atomization component, a mouthpiece and an airflow channel
  • the airflow channel comprises a vapor channel and an actuator airflow channel which are independent to each other, wherein the vapor channel is connected to atomization chamber of the atomization component and the mouthpiece, and open through to the atmospheric environment outside, wherein the actuator airflow channel is connected to the mouthpiece and open through to the atmospheric environment outside, wherein the pneumatic switch is arranged in the actuator airflow channel.
  • the advantageous effect of the present invention is that: the present invention provides an electronic cigarette which separate vapor channel and actuator airflow channel, the vape oil and condensate will not flow to the same channel as the actuator airflow channel and therefore cannot have any contact with the pneumatic switch, thus the life of the pneumatic switch is prolonged.
  • the adjustment of airflow volume in the vapor channel and the adjustment of sensitivity of the pneumatic switch which is positioned in the actuator airflow channel are not related and affected by each other. Accordingly, the flow rate in unit time of the vapor channel as well as the actuator sensitivity of the actuator airflow channel can be adjusted to suitable level and the comfort level of vaping is enhanced.
  • FIG. 1 is an exploded structural illustration of an electronic cigarette according to the preferred embodiment of the present invention.
  • FIG. 2 is an illustration of the airflow direction of a vapor channel and an actuator airflow channel of the electronic cigarette according to the preferred embodiment of the present invention.

  • the present invention provides an electronic cigarette (e-cigarette) device which comprises a battery component (battery is not illustrated in the drawings), an atomization component, a pneumatic switch 32 which control the start of the atomization component, a mouthpiece and an airflow channel, wherein the airflow channel comprises a vapor channel 28 and an actuator airflow channel 34 which are two channels independent to each other, wherein the vapor channel 28 are connected to atomization chamber 22 of the atomization component and mouthpiece 13 , and open through to the atmospheric environment outside, wherein the actuator airflow channel 34 is connected to the mouthpiece 13 and open to the atmospheric environment outside through an inlet 36 , wherein the pneumatic switch 32 is arranged in the actuator airflow channel.
  • the airflow channel comprises a vapor channel 28 and an actuator airflow channel 34 which are two channels independent to each other, wherein the vapor channel 28 are connected to atomization chamber 22 of the atomization component and mouthpiece 13 , and open through to the atmospheric environment outside, wherein the actuator airflow channel 34 is connected to the mouthpiece
  • one end of the vapor channel 28 and the actuator airflow channel 34 respectively are connected through to the atmospheric environment.
  • both of the vapor channel 28 and the actuator airflow channel 34 are open, the atmospheric air will enter to the mouth of a smoker through the actuator airflow channel 34 and will pass through the pneumatic switch 32 arranged in the actuator airflow channel 34 , the pneumatic switch 32 is turned on and the heating element 24 of the atomization component starts to operate, the heating element 24 processes the atomization of the vape oil which will flow along with the atmospheric air to the mouth of the smoker after atomization.
  • the pneumatic switch can detect the pressure changes inside the actuator airflow channel and operate, or can detect the impact of airflow and operate.
  • the working principle of the pneumatic switch is well known to the skilled in the electronic cigarette industry and is not repeated here.
  • the airflow passes through the atomization chamber 22 of the atomization component and its temperature will be increased.
  • the airflow may be condensed into liquid form when passing through the wall of the vapor channel 28 .
  • the liquid transmission element 23 may also contain vape oil.
  • the pneumatic switch 32 and the atomization component are not arranged in the same channel, therefore the vape oil and condensed liquid will not flow to the pneumatic switch 32 or cause damage to the pneumatic switch 32 .
  • the present invention prolongs the lifespan of the electronic cigarette.
  • the diameter of the opening of the actuator airflow channel 34 will directly affect the sensitivity of the pneumatic switch 32 .
  • the diameter of the opening of the actuator airflow channel is decreased, a sense of suffocation will be resulted when the vapor is inhaled. Therefore, the vapor channel 28 and the actuator airflow channel 34 which are combined together fail to take into account of the sensitivity of the pneumatic switch 32 and the sense of suffocation during vaping.
  • the present invention separates the vapor channel 28 and the actuator airflow channel 34 and solves the problem.
  • the atomization component comprises an atomizer support 14 , and a liquid tank 25 and an atomizer base 21 mounted securely inside the atomizer support 14 .
  • the atomizer base 21 is indented to define an atomization chamber 22 .
  • the atomization chamber 22 contains liquid transmission element 23 therein.
  • the heating element 24 in the form of heating wire is wound around the liquid transmission element 23 .
  • the liquid transmission element 23 has one end connected to the liquid tank 25 .
  • the atomizer support 14 has one or more vapor channel inlets provided thereon.
  • the atomizer support 14 has a side wall at an inner side and the liquid tank 25 has a side wall at an outer side.
  • the side wall at the inner side of the atomizer support 14 and the side wall at the outer side of the liquid tank 25 are arranged to form a first airflow channel, which is communicating with the vapor channel inlet, the atomization chamber 22 and the mouthpiece 13 so as to define the vapor channel.
  • the liquid tank 25 is made of transparent or semi-transparent materials so that the remaining amount of vape oil inside the liquid tank 25 can be seen conveniently.
  • the use of the side wall at the inner side of the atomizer support 14 and the side wall at the outer side of the liquid tank 25 to construct the first airflow channel is a simple structure and the cost of additional materials for its construction is eliminated.
  • the pneumatic switch 32 is arranged on top of the battery compartment body 12 and the pneumatic switch 32 is communicating with the actuator airflow channel 34 .
  • sealing pad 33 is provided at the peripheral edge of the pneumatic switch 32 .
  • the pneumatic switch 32 can be arranged at any position in the actuator airflow channel for the normal operation of the electronic cigarette. The reason for positioning the pneumatic switch 32 on top of the battery compartment body 12 is that the space availability on top of the battery compartment body is great and the production of electronic cigarette is facilitated.
